Further excellent testwork results for Speewah Fluorite Project Preliminary ore sorting testwork highlights potential to improve project economics
-
Excellent testwork results continue to be delivered for the Speewah Fluorite Project in Western Australia in support of Feasibility Study flowsheet design and engineering.
-
The latest comminution and flotation testwork program has returned grades of up to 99% CaF2 (versus acidgrade product standard of 97% CaF2) using new drill core obtained from the Q4 2024 drilling campaign, reinforcing flowsheet design.
-
Preliminary ore sorting testwork has also been completed delivering excellent outcomes, demonstrating rejection of 56% feed to the sorter with low fluorite losses.
-
Ore sorting offers potential to reduce process plant equipment sizing, water consumption, tailings tonnages, operating costs and sustaining capital costs.
-
Tivan has engaged Lycopodium and Orway Mineral Consultants to prepare a concept study for the introduction of ore sorting into the process flowsheet.
-
Acidgrade fluorite product samples are also being prepared by Tivan for end-users in Asia as part of the offtake marketing program with Sumitomo Corporation.
-
Tivan is advancing development planning for the project for a mining and processing operation of fluorite ore to produce acid grade fluorspar for export into global markets, in joint venture with Sumitomo Corporation and Japan Organization for Metals and Energy Security (JOGMEC).
The Board of Tivan Limited (ASX: TVN) (“Tivan” or the “Company”) is pleased to advise that Tivan has continued to deliver excellent testwork results as part of the program developed in support of Feasibility Study (“FS”) design and engineering for the Speewah Fluorite Project (“Project”) in Western Australia. Acidgrade fluorspar grades of up to 99% calcium fluorite (CaF2) were achieved, relative to the product standard specification of 97% CaF2, using diamond core sourced from the Q4 2024 drilling campaign (see ASX announcement of 8 November 2024).
The testwork results validate the previously announced outcomes of the 2024 optimisation program which delivered grades of up to 98.8% CaF2 (see ASX announcement of 19 March 2025).
Results of the testwork program are being incorporated into the FS underway for the Project and will support development of further metallurgical testwork required for the Definitive Feasibility Study (“DFS”) that will follow.
In addition, the Board of Tivan is pleased to advise that preliminary testwork has been completed to assess the amenability of the Speewah orebody to ore sorting technology. Ore sorting is a dry physical beneficiation process that is commonly used in the fluorite industry for upgrading crushed ore. For the Speewah Fluorite Project, ore sorting offers an opportunity to reject gangue (non-ore material) ahead of milling. The results from the ore sorting sighter test were very promising, achieving 56% mass rejection on a -31.5+10 mm sample.

Tivan is now investigating the potential for the introduction of ore sorting technology into the process flowsheet. Ore sorting offers a range of potential development, operational and economic benefits to the Project, including reduction of process plant equipment sizing (including the mill), water consumption, tailings tonnages, operating costs and sustaining capital costs, as well as a reduction in environmental impacts, including carbon emissions.
Testwork Overview
The core activities undertaken as part of this phase of testwork focused on the following key areas:
-
Variability testwork - to test different deposit lithologies and locations in support of FS engineering.
-
Optimisation testwork - to investigate the impact of alternative plant feed grades.
-
Ore sorting testwork - to assess potential for upgrading ore feed to the process plant.
The samples for testwork were prepared from four PQ diamond holes (SFM24_005, SFM24_006, SFM24_012 and SFM24_018) located in the A Vein of the deposit, sourced from the Q4 2024 drilling campaign (see Figure 1 below). The 2025 drilling campaign that is currently being progressed will provide additional drill core and samples across the full length of the deposit, in support of further planned testwork.

Sample preparation for the variability testwork involved a number of steps as detailed below. Selected intervals were crushed to -31.5 mm and homogenised to form composites representative of the vein and stockwork lithologies. Six of the composites were subjected to comminution testing including:
-
Abrasion index (“Ai”)
-
Bond Ball Work index (“BBWi”)
-
SAG Mill Comminution (“SMC”) tests
The vein and stockwork composites were then blended to form composites with varying head grades from 12.3% CaF2 to 20.3% CaF2. These composites were prepared for the following:
-
Rougher and cleaner deposit variability testing
-
Head grade variability testing
-
Rougher and cleaner optimisation testwork
-
Initial ore sorting testwork
-
Sample preparation for end-users
For the ore sorting testwork sample preparation, a composite was prepared with a head grade of 14.4% CaF2 which is lower than the life-of-mine-head grade of 17.25% CaF2 used in the July 2024 Pre-Feasibility Study (“PFS”) (see ASX announcement of 30 July 2024). The composite was screened at 10 mm, and the oversize (-31.5+10 mm) product was transported to ore sorting technology vendor TOMRA for the initial testwork.
Variability and Optimisation Testwork
The current phase of variability and optimisation testwork commenced in January 2025 and included both comminution and flotation testwork for the newly acquired core samples. All comminution and flotation testwork scopes have been conducted at ALS Metallurgy in Balcatta, Western Australia.
Comminution
Comminution testwork was completed for six samples in this program. The purpose of these tests was to acquire additional data to support and validate the PFS comminution circuit design. The BBWi, SMC and Ai data were in agreeance with historic data, resulting in only minor changes to the process design criteria. The results have provided initial validation of the selected comminution flowsheet.
Flotation Variability Program
The tests from this program were intended to both investigate deposit variability and validate the 2024 optimisation program outcomes (see ASX announcement of 19 March 2025). The following conclusions were notable:
-
Baryte rejection targets were achieved for all samples, including samples with elevated baryte. This is an excellent outcome which demonstrates areas of the deposit with elevated baryte can be processed.
-
Iron rejection targets were achieved for all samples with elevated iron, validating that the flotation parameters are suitable for processing the high iron lithology which constitutes 26% of the deposit.
-
Calcite and metal oxide targets were met for all of the samples tested.
==> picture [596 x 68] intentionally omitted <==
==> picture [596 x 127] intentionally omitted <==
-
SiO2 targets were met in one trial (refer below to the further flotation optimisation program results in addressing this outcome).
-
Fluorite grades were mostly within the 97% specification, with Si as the main impurity in tests where the target specification was not achieved.
Flotation Optimisation and End-User Sample Preparation Program
After review of the initial flotation results, a new testwork program was commissioned and a master composite was prepared from the same four holes as the variability program. The new testwork program was designed to address some differences seen in flotation behaviour for the 2024 PQ core. The final goal for this program is to prepare acidspar samples for potential end-users in Asia as part of the Project’s offtake marketing program with Sumitomo Corporation.
The changes introduced in this program realised immediate improvements in silica rejection. The grade and recovery data for the initial optimisation tests are summarised in Table 1 below. The initial results are excellent, achieving both the grade and recovery targets for the testwork program. More optimisation tests are planned to refine the rougher and cleaner flotation process further.
The following excellent outcomes were observed:
-
Demonstrated preparation of acidspar with ore head grades aligned with ROM head grade, de-risking the mine plan.
-
Achieved comparable results to the 2024 optimisation program, providing initial validation of those outcomes (see ASX announcement of 19 March 2025).
-
Utilising ore from the same holes as the variability tests, these tests demonstrated that the unanticipated SiO2 rejection in the variability trials could be resolved with minor modifications to the testwork parameters.

3 Fluorite grades and recoveries calculated based on impurities (see JORC Table 1 for details).
The recoveries presented in Table 1 are lower than the PFS design fluorite recovery of 90% and are an outcome of achieving a premium specification. The grade recovery curve for trial GJ2443 is presented in Figure 2 below: GJ2443 was selected for this example as the trial parameters are representative of the FS process design. The graph compares process recoveries for target grades of 97%, 98% and 98.4% CaF2. Fluorite rejected in the cleaner circuit is an opportunity for metspar recovery. An update for the metspar option development is provided below.

Ore Sorting Testwork
Ore sorting is a dry physical beneficiation process that is commonly used in the fluorite industry for upgrading crushed ore. For the Speewah Fluorite Project ore sorting is an opportunity to reject gangue (non-ore material) ahead of milling, offering the following potential benefits:
-
Smaller mill sizing.
-
Reduced environmental impacts including:
-
➢ Reduced water consumption
-
➢ Smaller tailings storage facility
-
➢ Less power consumption and carbon emissions
-
➢ Rejected gangue can potentially be reutilised for civil works during operations.
-
Reduced gangue rejection requirements for the rougher flotation circuit, potentially improving circuit reliability.
-
• Potential for smaller rougher flotation circuit.
-
Opportunity to lower the cut-off grade without modifying the pit shell to increase total fluorite production.
-
Sustaining capital and operating cost reductions.
A 25 kg ore sample was processed in TOMRA’s COM tertiary XRT system at their laboratory in New South Wales. The processed images of the test rejects, and the fluorite concentrate, are shown in Figure 3 below, where the blue is the target mineral.

Figure 3: Left: Ore sorter gangue rejects; Right: ore sorter fluorite product
The test successfully rejected 56% of the feed, resulting in an upgrade ratio of 1.8. As a percentage of the initial composite, the total fluorite rejected was 8.4% in the ore sorting test; however, subsequent downstream testwork indicates that a large proportion of the rejected fluorite would have otherwise been rejected by rougher and cleaner flotation and the true fluorite rejection percentage is therefore anticipated to be lower.
The upgraded fluorite concentrate was homogenised with the screen undersize (-10 mm) and subjected to rougher and cleaner flotation testwork. The grades of both acidspar products were ~94% CaF2 (F assay basis), which was below the target (97% CaF2) for the program. However, both tests had fluorite grade-recovery curves that support the conclusion that there is very high potential to meet the target acidspar grade with some optimisation of the flotation conditions. Work to address this is planned to be completed in Q4 2025.
Metallurgical Grade Fluorite By-Product
An opportunity to produce a metspar by-product was identified by Tivan and announced in the Speewah Fluorite Project PFS (see ASX announcement of July 2024). Lycopodium have now completed the concept study for three process flowsheet options and Tivan have selected one of the three options to be engineered for the FS. At this stage the metspar opportunity has undergone less testwork and engineering development compared to the rest of the flowsheet.
A testwork program is in planning for the cleaner flotation tailings generated from the end-user sample generation program described above.

Next Steps
Following completion of the current phase of testwork, the Company is planning the following related initiatives:
Ore Sorting Concept Study
Lycopodium and Orway Mineral Consultants have been engaged to prepare a concept study for the introduction of ore sorting into the process flowsheet. This study is being conducted in parallel with the FS and will conclude around the same time. The concept study will inform the decision on how to proceed with ore sorting and the Project flowsheet.
Sample Generation for End-Users
Optimisation testwork will continue into Q4 this year and will conclude with the preparation of acidspar samples for potential end-users in Asia.
Definitive Feasibility Study Testwork
Drill core from the current 2025 drilling campaign will be utilised for an expanded variability testwork campaign and ultimately for piloting. The results from these testwork programs will support engineering design for the DFS through to a Final Investment Decision.
Metallurgical grade fluorite (metspar)
An opportunity to produce a metspar by-product was identified by Tivan and announced in the PFS (see ASX announcement of 30 July 2024). Tivan are progressing the investigations into this opportunity with testwork and will update findings as part of the FS.
Tivan Executive Chairman Mr Grant Wilson commented:
“ Tivan is making sustained progress in de-risking the Speewah Fluorite Project and in building a new, critical export sector for Australia. By advancing the testwork program to a premium specification, we are providing strong support to the project’s marketing campaign in Asia, which is already well underway through our joint venture partner, Sumitomo Corporation.
Ore-sorting has emerged as a potentially viable development option through mid-year. As the opportunity is significant, our team is hard at work in assessing feasibility and in creating pathways to integrate the technology into the Project’s flowsheet. We look forward to providing further updates in this important area in due course, including in terms of applicability to the Sandover Fluorite Project.”
This announcement has been approved by the Board of the Company.

| Geology | • | Deposit type, geological setting, and style of mineralisation. | • | The Greenvale Fault forms the eastern |
| margin of the Kimberley Block and | ||||
| consists of a series of intersecting | ||||
| faults. Fluorite mineralisation is mainly | ||||
| hosted by north northeast and north | ||||
| trending faults within the Greenvale | ||||
| Fault, with minor occurrences along | ||||
| north trending normal faults within the | ||||
| Speewah Dome. The Early Proterozoic, | ||||
| Valentine Siltstone and Lansdowne | ||||
| Arkose of the Speewah Group host | ||||
| most of the mineralisation and outcrop | ||||
| as linear north northeast trending | ||||
| ridges. These sediments dip 10° to 20° | ||||
| to the SE. The other majorunit exposed |

| in the core of the dome is the Hart | |
|---|---|
| Dolerite (1703Ma), which was | |
| emplaced as a sill predominantly within | |
| the Valentine Siltstone. | |
| • | The predominantly white fluorite |
| mineralisation occurs mainly within | |
| tabular steeply dipping veins showing | |
| very good strike continuity often over | |
| several hundred metres in length. The | |
| veins range in thickness from less than | |
| 1m to 15m, often flanked by lower | |
| grade stockwork and stringer veins, | |
| forming an overall envelope up to 50m | |
| wide. | |
| • | The fluorite veins have been mapped in |
| three prospect areas known as Main | |
| Zone, West Zone and Central Zone | |
| over an area of approximately 160km2. | |
| Potential also exists under soil covered | |
| areas and in steep topographical areas | |
| within the district. In the Main Zone, at | |
| least nine fluorite vein sets have been | |
| mapped over a strike length of 8km. | |
| • | The following description is after |
| Crossing 2004 and SRK’s observations | |
| concur with the various mineralisation | |
| settings described. | |
| • | Fluorite is associated with quartz- |
| feldspar veining but is younger. It | |
| occurs in the various settings previously | |
| discussed: | |
| • | Large, persistent veins occupying the |
| main northerly and northeasterly | |
| trending structures. | |
| • | Fault breccias and brecciated veins |
| occupying the main structures. | |
| • | Stockworks and breccias hosted |
| preferentially by the sandstone and to a | |
| lesser extent by the dolerites adjacent | |
| to the main structures. | |
| • | En-echelon vein sets trending |
| northwesterly between structures. | |
| • | En-echelon vein set trending northeast |
| (rare). | |
| • | Thin persistent veinlets following |
| jointing mainly in the siltstones (rare). | |
| • | Thin persistent veinlets following |
| bedding planes in the siltstones (rare). | |
| • | The larger veins range in thickness up |
| to 15 metres and are up to 800m long. | |
| They have similar persistence down-dip | |
| within the faults and have been | |
| intersected in several holes as deep as | |
| 400m below surface, albeit it only in the | |
| order of 0.5m wide at that depth. | |
| • | The stockworks tend to occur adjacent |
| to the main faults and are dominantly | |
| hosted by the brittle sandstone unit, | |
| although reasonable stockwork veining |

| sometimes occurs in the dolerites. Best | ||||
|---|---|---|---|---|
| fluorite intersections occur where the | ||||
| main northerly trending faults contain | ||||
| fluorite in the form of veins and | ||||
| breccias, and the adjoining wall rocks | ||||
| (usually hanging wall) contain | ||||
| sandstone hosted stockwork veining. | ||||
| The en-echelon vein systems usually | ||||
| have a lower density of veining than the | ||||
| stockwork and hence a lower fluorite | ||||
| grade globally. | ||||
| • | The fluorite veins are younger and | |||
| crosscut the earlier quartz-feldspar | ||||
| veins, as seen in the photo above. They | ||||
| also often form co-axially in the center | ||||
| of the quartz-feldspar veins, and as | ||||
| vugh fill within them and in the matrix of | ||||
| quartz-feldspar vein breccia. Later | ||||
| carbonate veins crosscut all earlier | ||||
| features. Carbonate and quartz also | ||||
| infills voids in the fluorite veins, and | ||||
| occasionally quartz veinlets cut across | ||||
| fluorite veins. The fluorite is dominantly | ||||
| green to whitish in colour with less | ||||
| common purplish fluorite. In outcrop it | ||||
| weathers to grayish-white. It is | ||||
| generally coarsely crystalline often with | ||||
| euhedral crystals infilling open-spaces. | ||||
| The greenish flourite appears to be | ||||
| youngerthanthe purplevariety. | ||||
